PROCESS 'OF MAKING 'LTNOTYPE-SLUm..

.Toallrwhomit may canoe-m:

.. .Be it known that .I, HARRY C. GAM ETER, a citizen of the United .States, residing at Cleveland,'.in .the county .of Cuyahoga and State of Ohio, :have invented .a .certain {new and useful Improvement in Processes of Making Linotype-Slugs, of which the following is a full, clear,.and exact-description, reference being .had to the accompanying drawings. p v

The objectof'this invention-isle provide for'the very cheap manufacture of linotype slugs grooved "on their opposite sides and standing a short height-to-paper.

My invention includes a process for male in% such slugs accurately and cheaply. riefly','the process consists of casting a slug with a=projecting head, the loweredge :of which is to form the. ultimatebottom of ggatheslug and thengroov ing the sides of such liead'and removiligfihe shank so that the short slug may tand on the east surface.- EB yTmaking the lug so that thesupport .eomes onanlori'gi'nal .castlsnr'face'aecuracy Fig. 4 may. be used in any suitable printing is obtained, and the grooves,which are for the *purpose .of retaining slugs in their 'holder,=rnay be cheaply; and quickly made by anyconvenient machine. v In removing the shank of'the slug I remove it to a point within the body of the head; that is, I provide a groove'on the bottomoftheshort slug so that the pressure will certainly come on an original cast surface.

My invention is hereinafter more fully explained in connectio'n with the drawings hereof and its essential characteristics are summarized in the claims.

"In the drawings, Figure 1, is a section of the mold wheel, the melting pot and the matrix of -a Merg'enthaler linotype machine having a special mold; Fig. 2 is a perspective-view of a slug as cast by the mold i shownin Fig.1; Fig. 3 is a cross section of "gthe head portionof such originalislug after 45.;the majonportion of the shank has been removed; Fig. 4 isa perspective viewofthe i finisliedslug. o g F: Ref rring to'the parts by numerals [finall ppositeiihe slot in the' mold.

This rib 12is then milled or planed away to insurethe slug standing on the surfaces 14, .which are cast surfaces. I earry the milling of the rib 12 to the point where it makes a groove 15 in the base of the short slug. Grooves 16 are of the short slug. The two grooves 16 and the groove 15 may conveniently be'made at the sametimeby simple mechanism. gMy finished'slugs ofthe forin shown in holder which allows the slug to stand on its own basef To insure its standing on its base portion 14,- thevside grooves 16 are made of greater height than the material of the Such holder may be the rails of ,a drum or segment, as usedon the Multigraph, or a slotted plate for addresses, of other form. The holder is simply for the purpose of retaining the slugs in posi tion on the support against which the base of the slug bears and which receives the printing pressure. When in operation, .the

shape, the head having continuous up-and- ;d lL surfaces whereby "it may be ejected from zt fixed mold and having the desired fheight paper and .then ,ieinoving the shank of the T to allow the head to stand on the cast underfaee thereof and grooving the opposite sides of the heads v2. The process of making line slugs conformed by milling, or otherwise,.in the sides i sisting of casting the slug in the form of a T, and-thereafter removing the shank of the T and grooving the head thereof.

3. The process of making line slugs consisting of casting the slug in a form having a 'T cross section, and then removing the shank of the T and grooving the opposite sides of the" head thereof.

4. The process. of making line slugs consisting of casting 'the slug in the form of a T, the head of which is uninterrupted in an up-and-down. direction, then removing the shank of the slug and forming a groove in the base of the remaining head where the shank projected to insure cast surfaces being the only supporting bottom of there-. maining slug, 'and making a-longitudinal groove in the side of the head.

5. The process of makin line slugs consisting of casting the slug in a T form and thereafter removing the shank of the T and grooving the base of the remaining head where the shank projected, and grooving the opposite sides of the head.

6. The process of making iow-height line slugs adapted to be held between overhanging rails and rest on a cast surface consisting of casting in a fixed mold a higher slug with a shank and an overhanging head, the height of the head being the height of the finished low-height slug and said head having its sides free from longitudinal grooves, then ejecting said slug from the mold by pressure against the foot of the slug, then removing the shank below the head and -grooving the opposite sides of the head.
